ERNEST SMITH WALKER, OF ST. JOFHN, KANSAS, ASSIGNOR OF FOR'lY-NINE ONE- I-IUNDREDTHS TO CHARLES VAN'FLEET, OF ST. JOHN, KANSAS. i

RADIATOR.

Application filed March 29, 1922.

To all whom it may concern:

Be it known that I, ERNEST SMITH WVALKER, citizen of the United States, residing at St. John, in the county or" Stafford and State of Kansas, have invented certain new and useful Improvements in Radiators, of which the following is a specification.

This invention relates to an improved radiator for internal combustion engines and seeks, as one of its principal objects, to provide a radiator which will be formed of sections so that should any one of the sections become injured or otherwise damaged, the radiator may be readily repa1red.

and bottom tanks so as to form tight joints therewith while slight displacement of the units, in the operation of removing said units, will serve to free the units with respect to said tank so that said units may then be easily withdrawn.

.And theinvention has as a still further object to provide a radiator well adapted for use in connection with various prevalent makes of motor vehicle engines.

Other and incidental objects will appear hereinafter. I

In the drawings:

Figure 1 is a front elevation ofmyinr proved radiator,

Figure 2 is a vertical sectional View on the line 2-2 of Figure 1, looking in the direction of the arrows,

Figure 8 is a horizontal sectional view on the line 33 of Figure 2, looking in the direction of the arrows,

Figure 4t is a perspective view of the radiator showing the core units removed and the top tank detached.

Figure 5 is a fragmentary detail sectional View particularly bringing out the manner Serial No. 547,885.

in which the top radiator casing.

Figure 6 is a detail perspective view showmg one of the emergency closure plates employed. 1

In carrying the invention into efiect, I employ a casing including a bottom tank 10 having a top wall 11 anda bottom wall 12 extended upwardly at the ends of the tank to form supporting brackets 13 for the tank is connected with the radiator, said brackets being designed for attachment to the side bars of a motor vehicle chassis frame" for mounting. the radiator upon the frame; The top-wall 11 of the tank is provided with a plurality of openings 14-; therein and connected with the bottom wall is an outlet pipe-15. Rising from the tank at itsextremities areside plates 16 reduced at their upper ends to form inwardly curved resilient tongues .17]

and extending from said, plates are side flanges 18. Fitting between said flanges are reinforcing strips 19 which are preferably of wood although said strips may beformed of metal and overlying said strips are channel plates 20, the side flanges of which fit between the flanges 18 mating therewith.

In the present instance, I have shown the casing of a size to accommodate a' pair of the core units or sect ons employed and raising from the topv wall of the bottom tank 10 medially thereof, is a vertical partition 21 for separating said units.

However, as will be appreciated, the casmg maybe enlarged to accommodate any number of core units desired and, in such instance, a. partition will be provided between each pair of the units. Detachably connected to the side plates 16 is a top tank 22 resting at its. ends, shown in detail in Figure 5, upon the upper ends of the reinforcing strips 19. This top tankj overhangs the bottom tank at its inner edge and is formed with an oval-shaped top'wall 23 to which is secured a pair of'spaced keepers 24: at each end otthe tank. As best shown in Figure 5, the tongues 17 of the side plates 16 are engaged through thesekeepers for detachably securing the top tank in position, being curved longitudinally to lie fiat against the curved top wall of the tank, and due to the resiliency of the tongues, said tongues will operate to clamp the top tank against the upper ends of the reinforcing strips 19 so as to prevent rattling. Gonzoo neot-ed to the inner end wall of the top tank is an inlet pipe 25 and rising from the top wall of the tank is a filler tube 26 normally closed by a cap 27. Mounted upon the tank at the bottom thereof is a bottom plate 28 forming a portion of the bottom wall of said tank and provided with a plurality of openmgs 29. As particularly shown in Figure 2, this plate is tapered from its rear by a bottom plate 32 and at their upper ends by a top plate 33. Mounted upon said tubes are appropriate fins 34L. Positioned between the bottom plates 32 of the units and the top wall 11 of the bottom tank 10 are, shown in Figures 2 and 4:, suitable gaskets 35 and positioned between the top plates 33 of the units and the plate 28 of the top tank are similar gaskets 36. These gaskets are all of like construction and attention is now direc-ted to the fact that the top plates 33 of the units are tapered from their forward edges toward their rear edges and are accordingly formed with upper beveled faces 3'6 mating with the beveled face of the plate 28. Accordingly, as each of the units is moved lnwardly into the casing said unit,

will wedge between the top and bottom tanks for compressing the gaskets and" 36 to form sealed joints between the units and said tanks firmly binding the units in position the tubes of the units registering with. the

openings 14 and 29 of the top wall 11 of the bottom tank and the plate 23 of the top tank respectively when the units are inplace. At the same time, the units may be readily withdrawn individually at the forward side of tlie casings-11d after said units have been shifted forwardly out of wedging engagement between the tanks, said units will be freed so that the units may be easily displaced. Formed in the rear margins of the top and bottom plates of said units are, as shownin Figure 3, slots 37 and extending through said slots are cap bolts 38 threaded into the wall 11 ofthe bottom tank and the plate 28 of the top tavnkfor securing the units at their rear sides. Extending through the forward margins of the plates 32 and 33 are cap bolts 35) also threaded into the wall 11 and plate 28 for securing the units at their forward sides. Thus, by loos ening the bolts 38 and removing the bolts 39, the-units may be withdrawn. 1 accordingly provide a construction whereby should one of the units of the radiator become damaged or otherwise impaired, such unit may be easily renewed without molesting the other units of the'radiator.

, Hingedly mounted upon the casing at its forward side is a screen 40 normally held closed by cap bolts ll sov as to provide protection for the core units atthe front of the radiator and protecting said units at the rear of the radiator is a screen comprising a fixed section 42 uponv which are mounted hinged sections normally held. closedby stud bolts 4% preferably carrying wing nuts, the section 4-2 being detachably secured in any approved manner upon the sides of the casing. It will accordingly be seen that I provide a radiator of particularly eflicient construction and, as will now be appreciated, a radiator well adapted for a wide range 0' use.

In conjunction with the radiator casing, I provide emergency closure plates 45' which, as shown in detail in Figure'h, are provided at corresponding ends thereof with slots 4:6 to accommodate the bolts 38 and at their opposite ends with openings d7 to accommodate the bolts 39. Accordingly, if, in the practical use of the radiator upon a vehicle, one of the core units should become injurec whileupon the road where it would be impossible to repair the unit, such unit may be removed when a pair of the plates 45 may be employed to close the openings 14: and 29 in the top and bottom tanks exposed by the removal of said unit, the plates being clamped down against the exposed gaskets and 36 forming sealed joints therewith. Having thus described the invention, what is claimed as new is v I An engine radiator including a bottom tank having side plates rising therefrom and provided with tongues, a top tank having keepers thereon accommodating said tongues, the tongues detachably connecting the top tank with saidplates, and a coreunit fitting between the tanks con'imunicating therewith. 4 i

In testimony whereofI aflix my signature.
